Adhesive for Solar Photovoltaic Panel Backsheet

AS 9450/AS 9400H adhesive for solar photovoltaic panel backsheet is a high-performance special bonding solution specially developed for the lamination scenario of solar photovoltaic panel backsheet films. It focuses on the core needs of long-term outdoor use of photovoltaic backsheets, accurately adapts to the multi-layer composite structure of photovoltaic backsheets (Silicon Wafer + Encapsulant Film EVA/EVA + PET + PU + PVF), adopts a dual-process adaptive design of dry lamination and flexo lamination, can quickly adapt to the photovoltaic backsheet production line, and provides firm, stable and long-term bonding guarantee for the lamination of various layers of photovoltaic backsheet materials. As a high molecular weight polyester product, the formula is professionally optimized, with excellent yellowing resistance, weather resistance and high temperature resistance. The colloid is flexible and has outstanding elongation performance, which can easily adapt to deep drawing and other processing procedures in photovoltaic backsheet production. At the same time, it passes strict aging tests and can resist the impact of harsh outdoor environments such as long-term sun exposure, rain, alternating high and low temperatures, and ultraviolet radiation. The product has high initial tack and high peel strength, fast bonding forming speed, effectively improving the production efficiency and product qualification rate of photovoltaic backsheets, ensuring the sealing and barrier properties, structural stability and long-term durability of photovoltaic backsheets, adapting to the packaging needs of various crystalline silicon solar cell modules, helping photovoltaic modules achieve long-term stable operation for more than 25 years, and providing reliable bonding support for the utilization of solar clean energy.
